Knox County is acounty located in theU.S. state ofTennessee. The population was 506,748 as of a 2024 estimate, making it the third-most populous county in Tennessee. Itscounty seat isKnoxville,[4] which is the third-most populous city in Tennessee. Knox County is included in theKnoxville metropolitan area. The county is located at the geographical center of the Great Valley ofEast Tennessee. Near the heart of the county is the origin of theTennessee River, at the confluence of theHolston andFrench Broad rivers.
In 1783,James White and Francis Alexander Ramsey led an expedition to explore the Upper Tennessee Valley, now within the boundaries of Knox County. White moved to what is now theRiverdale community on the banks of theFrench Broad Riverin the eastern part of the county in 1785, and the following yearconstructed a fort a few miles to the west. A community developed around the fortified trading post, ultimately becoming the city of Knoxville. Governor Blount designated the fort as the capital of the Southwest Territory in 1790, and gave the new town the name "Knoxville" after his superior, Henry Knox.[6]
Blount began construction of his house,Blount Mansion, in the early 1790s. This is one of a number of late eighteenth-century structures that have been preserved in the county. The house still stands in downtown Knoxville. TheAlexander McMillan House, built in the mid-1780s by Alexander McMillan (1749–1837), still stands in eastern Knox County. TheAlexander Bishop House, built by Stockley Donelson in 1793,[7] and a log house built in the same year by Nicholas Gibbs both still stand in the northern part of the county.[8] Campbell's Station, a fort and stagecoach stop located in what is nowFarragut, was built by Captain David Campbell (1753–1832) in 1787.[9]John Sevier established a plantation, known asMarble Springs, in the southern part of the county in the 1790s.[10] He was active in leading raids against theCherokee people, who for years resisted with force American settlement in their territory.

Important railroad lines passed through Knox County, making it a strategic area both for Union and for Confederate forces throughout theCivil War. Since the mountainous terrain of East Tennessee was mostly unsuitable for plantation crops such ascotton,slavery was not as prevalent as it was in Middle and West Tennessee. The US 1860 census of Knox County showed a population of 20,020 white citizens and 2,370 enslaved African Americans.[11] The lack of slavery combined with the vestiges of a once-strong abolitionist movement were two reasons most residents of Knox County, along with much of East Tennessee, were pro-Union. In February 1861, 89% of Knox Countians voted for the pro-Union ballot in a statewide referendum onsecession. On June 8, 1861, the county voted against Tennessee's Ordinance of Secession by a margin of 3,108 to 1,226.[12]
Prior to secession, Unionists from Knox County collaborated with other East Tennessee Unionists in an attempt to secede from Tennessee itself and remain part of the Union.Oliver Perry Temple, a Knoxville lawyer, was named to a three-man commission to appear before the General Assembly inNashville and request East Tennessee and pro-Union Middle Tennessee counties be allowed to secede from the state.[13] The attempt failed. After the second state referendum for secession passed in 1861, Knox County and the rest of Tennessee joined the Confederacy.[14]
Knox County remained under Confederate control until September 3, 1863, when GeneralAmbrose Burnside and the Union army marched into Knoxville unopposed. Parts of Middle Tennessee had been occupied by Union troops since 1862.
Union Colonel William Harris, son of New York SenatorIra Harris, wrote his father:[11]
'Glory be to God, the Yankees have come! The flag's come back to Tennessee!' Such were the welcomes all along the road, as we entered Knoxville, it was past all description. The people seemed frantic with joy. I never knew what the Love of Liberty was before. The old flag has been hidden in mattresses and under carpets. It now floats to the breeze at every staff in East Tennessee. Ladies wear it – carry it – wave it! Little children clap their hands and kiss it.
With the success of Burnside's troops in theKnoxville Campaign, and especially during the decisiveBattle of Fort Sanders, Knox County remained under Union control for the duration of the Civil War.
The XVI on the Knox County Seal is a nod to Tennessee becoming the 16th state. The late 19th and early 20th centuries, Knox County was an important venue for the quarrying and finishing ofTennessee marble, a type of limestone used in monument construction across the United States and Canada. Eleven quarries were operating in Knox County in 1882, and within ten years that number had doubled. Notable quarries in Knox included the Bond Quarry inConcord, an Evans Company quarry near Forks-of-the-River, and the Ross-Republic quarries nearIsland Home Park inSouth Knoxville. Finishing centers were located inLonsdale and at theCandoro Marble Works in South Knoxville.[15][16]

According to theU.S. Census Bureau, the county has a total area of 526 square miles (1,360 km2), of which 508 square miles (1,320 km2) is land and 18 square miles (47 km2) (3.4%) is water.[17] The county lies amidst theRidge-and-Valley Appalachians, which are characterized by long, narrow ridges, oriented northeast-to-southwest, alternating with similarly shaped valleys. Notable ridges in the county includeBays Mountain, McAnnally Ridge, Beaver Ridge,Sharp's Ridge and Copper Ridge.House Mountain, at 2,064 feet (629 m), is the county's highest point, and is the focus of a state natural area.[18]
The Holston and French Broad rivers join to form the Tennessee River in the eastern part of the county, an area known as "Forks-of-the-River." This section of the river is part of Fort Loudoun Lake, which is created byFort Loudoun Dam on the river several miles downstream inLenoir City.
Cherokee Caverns is 14 miles west of Knoxville and can be accessed by Highway 62. It was discovered in 1854 by Robert Crudgington, who noticed fog emerging between rocks on his farm. He dug the entrance open and explored the cave. His daughter Margaret Crudgington opened the cave to the public in 1929 under the name Gentrys Cave; the next year she changed the name to Grand Caverns.
The cave has been open to the public, sporadically, ever since, under a variety of names. It is currently called Cherokee Caverns, referring to the historic tribe who occupied this area at the time of European encounter.[19]
Indian artifacts located in the cave indicate that another entrance to the cave existed at some time in the past.[19]

Thecounty mayor is the head of the executive branch of Knox County Government. The current county mayor isRepublican professional wrestler Glenn Jacobs, better known by hisWWE personaKane. According to the county charter, the mayor serves as the chief financial officer of the county, responsible for developing the county’s annual budget, approving contracts, and overseeing county operations. Other duties include maintaining county roads, highways, and bridges, enforcing codes, operating the county health department and public library system, and supervising various executive branch departments.[31]
The mayor has the authority to veto resolutions and ordinances passed by the Knox County Commission. A majority-plus-one vote of the commission is required to override a mayoral veto unless the vetoed legislation originally required a two-thirds vote, in which case a two-thirds vote is required to override.[32]
Knox County administers the local school and library systems, while Knoxville maintains an independent police department separate from the county sheriff. The property assessor’s office, tax offices, and the Metropolitan Planning Commission are combined between city and county governments. All county elections are conducted on a partisan basis. County commissioners’ districts do not correspond with the city ofKnoxville, which has its own mayor and city council. Residents living within Knoxville city limits vote in both city and county elections, are represented by both mayors, and pay city and county taxes. While some administrative functions may appear duplicated, services are generally separated.[33]
The Knox County Board of Commissioners is the legislative body of Knox County and consists of 11 members: 9 elected at the district level and 2 elected countywide to serve at-large.[34] Commissioners meet multiple times each month, with their primary business meetings being a monthly work session and a monthly voting meeting. During the work session, commissioners generally debate items on the monthly agenda and take a non-binding vote on each item in advance of the more formal voting meeting, which is generally held the following week.[35]
The Board of Commissioners approves resolutions, ordinances, honorariums, road names, as well as most county contracts and large expenditures. Resolutions require a single vote for passage, while ordinances require two votes, or "two readings". The County Commission also serves as the appropriating body of the county and must approve an annual budget – presented by the mayor – which includes funding for the various county departments, including theKnox County Schools. The body also sets the property tax rate for the county.[35]
The board currently has a Republican majority, with 8 Republicans and 3 Democrats as of the 2024 elections.[36]
Public education in Knox County is overseen by the Knox County Board of Education, which governs the Knox County Schools. The board consists of nine members elected from single-member districts, serving four-year terms. These districts use the same boundary lines as the Knox County Commission, representing residents of Knoxville, the Town of Farragut, and all other areas of Knox County.[37]
Members represent residents of Knoxville, the Town of Farragut, and other areas of Knox County.[38][39]
The board acts as a single governing body, making decisions that apply to the entire school system. Its responsibilities include setting policies for Knox County Schools, approving the annual school system budget, appointing and supervising the Superintendent of Schools, and selecting a chair and vice chair from among its members each year.[38]
The board currently has a Republican majority, with 5 Republicans and 4 Democrats as of the 2024 elections.[40]
Like most counties in heavily-Unionist East Tennessee, Knox County has historically been strongly Republican. Although it is conservative for an urban county, it is notably less Republican than most of the rest of East Tennessee. This is largely due to the influence of Knoxville, which in recent years has had a tendency to vote Democratic in statewide races,[41] has elected Democratic mayors, and regularly elects Democrats to the state legislature. However, the suburban and rural areas are among the most Republican areas of Tennessee and the South.
Presidentially,Franklin Roosevelt carried the county in three of his four presidential elections, while several nearby counties are among the only counties in the nation to have never supported a Democratic candidate for president in their entire existence. Nevertheless, Democratic candidates have crossed the 40-percent mark only seven times since Roosevelt's death. In 1964, it was nearly swept up inLyndon Johnson's national landslide; Johnson lost the county by only 334 votes.Jimmy Carter in 1976 andBill Clinton in 1992 and 1996 are the only Democrats since then to come reasonably close to carrying the county, losing it by single-digit margins; in Clinton's case with TennesseanAl Gore on the ticket. Gore lost the county by 17 points in 2000 during his own bid for president, but still managed 40 percent. The Democrats would not cross the 40 percent threshold again until2020, whenJoe Biden received over 41 percent of the county's vote.[42]
